In November 2015, two heat-conducting oil fires occurred in Wujin, Changzhou and Liyang respectively. The heat-conducting oil fire accident in Wujin Chemical Plant happened in the waste boiler. With the flow of heat-conducting oil, the fire spread continuously. The firemen immediately dispatched two foam guns to put out the fire. The main reason is that when the old boiler was dismantled, the heat conduction tubing was accidentally welded through, and the spark ignited the heat conduction oil. In addition, the fire accident in a chemical factory in Liyang was caused by the ruptured thermal conductive oil pipe. The leaking thermal conductive oil was quickly burned by open fire, and the fire was also extremely fierce. According to the situation on the scene, the firefighters immediately dispatched foam guns to control the fire, which lasted for three hours and eliminated the danger.

Although the two accidents were put out by firefighters with all their strength and no casualties were caused, the occurrence of the accident not only affected the normal production operation of the enterprise, but also related to property and safety. Therefore, in order to ensure the normal, safe and stable operation of the thermal oil system, we need to consider many factors, including the quality of the thermal oil and oil products, the reasonable design of the thermal oil system and the daily safe use specifications.

The quality of thermal oil is the core of safe operation of thermal oil system. The use of unqualified heat-conducting oil products or products not approved for use and products without production qualification will result in the oil products reaching the scrap standard in a short period of time. If continue to use there will be a certain risk of accident, the light coking aging oil change, the heavy burning through the furnace tube, causing fire and other accidents. Therefore, the selection of high quality thermal oil is an important guarantee to reduce the occurrence of accidents. The ideal thermal oil should have high flash point, high spontaneous ignition point, good fluidity, low carbon residue, high heat transfer efficiency, wide application range and good thermal stability.

In addition, unreasonable design and installation of the thermal oil heating system will lead to unbalanced flow rate of thermal oil in the furnace tube and local overheating phenomenon during operation, which will lead to aging and deterioration of thermal oil and oil.

At the same time, daily safe use is the guarantee of safe operation of thermal oil system. In the process of operation, if the operation is not carried out in accordance with the rules, the abnormal phenomena such as overtemperature and overpressure of the system cannot be found in time, or the corresponding measures are not taken when the furnace is shut down in an emergency, then the quality and service life of the thermal conductive oil will be directly affected, leading to deterioration of the thermal conductive oil and coking in the furnace tube. Therefore, the enterprise needs to cultivate professional heat conduction oil furnace operation personnel, strictly abide by the "boiler safety technology supervision regulation and ban the irregularities and overtemperature operation, import and export temperature difference often observe the system pressure and heat conduction oil furnace is abnormal, pay attention to the high tank liquid level, strengthen the patrol system pipeline, prevent the pipeline leak and mixed with the material. On this basis, to ensure the quality of oil, stable production and property safety.

In order to enable users to use more high-quality thermal oil products and ensure more stable and safe operation of the system, Hanni Chemical proposed a 360-degree all-directional, full-life cycle service mode, including pre-sale, in-sale and after-sale three stages. From pre-sale service of technical support, product selection, technology sharing, to the sale of services use debugging, training, wash, customized logistics system, and then to after-sales service of periodic diagnosis, free testing, troubleshooting, renewable products, so that your system is always in the best running state, no worries, more easy to deal with challenges.
